I know that a lot of people don't like dogs. And that's OK. But having a 15 week old dog, we're trying to socialise, we took him on the bus. A family got on about 3 stops in, and every single one screamed at the sight of him, asleep under my seat, and spent the journey squeaking every time he moved ie turned over, or scratched, or shook his head.
I think, why? If you don't like dogs, that's fine, he wasn't bothering people, he was asleep, under full control and not interested in them in the slightest.
